It's an awesome fish, it's pretty cool that the river even has resident rainbows that get that big. This sounds like the progression that 99% of steelheaders go through. Namely, not catching shit for a while. The fact that you're getting hook ups means it's only a matter of time. Those hookups are the positive feedback to let you know that you're doing the right things. Be stoked for catching that rainbow, the excitement is one of the great parts don't let the internet crap on it. I still get excited if I catch a big whitefish, it's all fun.
